In recent years, the biggest black horse in the screw air compressor market (water lubricated screw air compressor) is a new type of air compressor equipment. Whether it is working principle or lubrication method, it is quite different from the traditional screw air compressor.
shanghai granklin group for your detailed introduction under the oil and water lubrication screw air compressor working principle and advantages.
Basic principle: a cylindrical screw and two symmetrical configuration of the plane star wheel meshing pair. Usually there are six screw grooves on the screw, and each star tooth divides the screw groove meshing with it into two spaces.
Each realizes the working process of the compressor. Because there are two star gear teeth, the single screw compressor is equivalent to a six-cylinder double-acting piston compressor. Because the cylindrical screw and the star wheel symmetrical cortex, so that it has a balance, so its axial force and radial force can cancel each other. This is a prerequisite for the normal operation of the machine for a long time.
features and advantages of oil-free water lubrication screw air compressor
1, reasonable structure, with ideal force balance
each side of the screw of the oil-free air compressor is equipped with a star wheel symmetrical structure, so that the oil-free air compressor not only has no unbalanced inertial force, but also the axial force and radial force used on the screw cancel each other out to make it have ideal force balance.
2, high efficiency
in theory, the oil-free air compressor has no clearance volume, large single machine capacity and ideal isothermal compression. Due to the good thermal conductivity of water, the temperature of lubricating water will drop to 45 ℃ when it is injected into the compression chamber, close to the suction temperature.
3. Compressed gas does not contain oil
replacing oil with water to achieve lubrication, cooling, sealing, noise reduction and other effects, providing high-quality oil-free air, no pollution, and the discharged water does not require special treatment to meet environmental protection requirements
4. Low noise and small vibration
the superior power balance system of the oil-free air compressor can effectively suppress the vibration source, and the operation is stable. There is no special requirement for the foundation. The star wheel adopts a special customized polymer material. The working cavity is sprayed with lubricating water intermediate transmission gear, so the operating noise is low.
5, the host long life
the symmetry of the structure and the possibility of arranging the flow holes allow the radial and axial forces generated during the operation of the compressor to be balanced, so that the rotor bearing can run for 50000 hours with a small load.
The above is the introduction of the working principle and advantages of the oil-free water lubrication screw air compressor.
features
compared with other forms of oil-free air compressor, oil-free water lubrication air compressor has obvious advantages:
1, the use of water as a compression seal, cooling medium, the use of low cost.
Through advanced sealing and isolation technology, the compressed air is cleaner and can be pure oil-free.
3, the volumetric efficiency is higher, more energy-saving, more than two dry twin screw energy saving more than 15%, more than a dry twin screw energy saving more than 36%.
4, to avoid frequent dry screw, high host maintenance, more stable and reliable.
5, lower noise, single screw axial and radial force balance, star wheel in the water film lubrication with the screw free rotation, so the host components in low load smooth operation, to ensure low noise and durability.
6, compared with the traditional air compressor to save lubricating oil and oil filter and oil and gas separation core and other consumables, thereby reducing maintenance costs (one year is the traditional micro-oil air compressor 1/5 maintenance costs)
7, no oil, so the use of more environmentally friendly.
Applicable industry
(1) Medicine.
(2) The food industry.
3, photovoltaic products and new energy.
4. High precision instrument.
5 The hospital.
Other factories that require high-quality compressed air.
The solution to the water in the air of the air compressor is as follows: 1. There is a drain valve at the bottom of the air compressor cooler. As long as the drain valve is opened immediately, the water inside can be drained clean. 2. You can also install a drain valve at the lowest end of the air compressor storage tank, or
In the application of some special scenes of compressed gas, we need to use explosion-proof ability of "explosion-proof air compressor", but most people only know "explosion-proof air compressor", but do not know what is "explosion-proof air compressor".
